okay so i have been working out for a little over a month now, usually i work out at my school gym and go on the eliptical, but the past two days i have began running, both on the treadmil and outdoors on a track in a forest. I started spotting a dark brown color about two days ago and have not stopped. Now my discharge is a brownish red mix. I have not had sex within this time frame and i have been on birth control for probably over a year now, and i am starting to get nervous i could have a STI or something? Why is this happening? If anyone can offer any suggestions to why this could be happing pleasee let me know!
More than the exercise, which doesn't seem to be in any way excessive or strenuous to me, birth control could be the reason for this spotting, even after a this long time being on BC. If this is happening after your regular bleeding, than dark brown discharge is just residual, old blood from that bleeding, but if there is a chance that you might have contracted STD, than you should definitely get tested. But, as I said, birth control has direct effect on your ovulation and on the uterus tissue that breaks apart and causes bleeding during regular menstrual cycle, so it's quite possible that BC is responsible for the spotting.
